Human IGF-II (Receptor Grade), recombinant protein

Product Specifications Human IGF-II:

The Product: Human insulin-like growth factor-II (IGF-II) is a 67amino acid polypeptide that stimulates growth and differentiationin many cell types.

Source: IGF-II is synthesized in E. coli using a patented expression system and harvested from the cells as inclusion bodies. The inclusion bodies are dissolved, desalted, the IGF-II is correctly folded under oxidising conditions and then a short leader peptide is cleaved from the peptide product. Several liquid chromatography purification steps are employed to yield receptor grade IGF-II.
